Free Space Optics (FSO) provide a cost-effective, license-free, high-bandwidth and long-range solution to meet the escalating demand for wireless network capacity and scalability. This project aims to develop technologies for robust FSO networks from the network and cross-layer optimization perspective. Various network dynamics will be addressed with the following approaches. (i) For dynamics at large timescales, network planning and topology optimization will be investigated based on the concept of algebraic connectivity. (ii) For mid-timescale dynamics, effective load balancing and adaptive multipath routing will be developed. (iii) For small timescale dynamics, channel estimation will be investigated to enable rate adaptation and optimal receiver design. Wavelength diversity will also be exploited for the diversity-multiplexing tradeoff.If successful, this project will enable scalable wireless access networks with multi-gigabit rates, to accommodate the predicted increase in wireless data. Project outcomes will be disseminated and incorporated into the Auburn University Wireless Engineering curriculum. The PIs will strive to involve REU students, and to participate in Auburn?s TIGERs Camp for outreach to K-12 students. The PIs have collaborations with an HBCU on research, curriculum, and recruiting minority graduate students.This is a timely project given the imminent explosive increase in wireless data. This project is of high risk, due to the lack of measurement data in the public domain and the novel approach taken in this research. This project is also of high payoff. If successful, it can bring about the much needed technologies for high rate, long distance, and scalable wireless access networks.

自由空间光学（FSO）提供了一种具有成本效益、免许可、高带宽和远距离的解决方案，以满足对无线网络容量和可扩展性不断增长的需求。该项目旨在从网络和跨层优化的角度开发健壮的FSO网络技术。各种网络动态将通过以下方法来解决。(i)对于大时间尺度的动态，网络规划和拓扑优化将基于代数连通性的概念进行研究。(ii)对于中期动态，将开发有效的负载平衡和自适应多路径路由。(iii)对于小时间尺度的动态，信道估计将进行调查，使速率自适应和最佳的接收机设计。如果成功，该项目将实现具有多千兆比特速率的可扩展无线接入网络，以适应无线数据的预期增长。项目成果将被传播并纳入奥本大学无线工程课程中。PI将努力让REU的学生参与进来，并参加奥本？的老虎营外展到K-12学生。PI与HBCU在研究，课程和招募少数民族研究生方面进行了合作。考虑到无线数据即将爆炸性增长，这是一个及时的项目。由于缺乏公共领域的测量数据和本研究采用的新方法，该项目具有高风险。这个项目也是高回报的。如果成功的话，它可以为高速率、长距离和可扩展的无线接入网络带来急需的技术。
